Elizabeth Bruch, currently an Assistant Professor in Sociology and Complex Systems, will officially become an Associate Professor in September 2017. Bruch’s work covers a range of population phenomena in which the actions of individuals and other units (e.g., families, couples neighborhoods) are dynamically interdependent. Most of her work blends statistical and agent-based methods. She is currently working on issues related to mate preferences and marriage market dynamics; income inequality and income segregation; modeling of residential choice; and the role of scale (population and group size) in social dynamics.
